president, and i've talked about how we need to create jobs, the importance of development, global health, the fight against hiv-aids, to growth that leads nations to prosperity. we talked about development and how it has to include women and girls, because by every benchmark, nations that educate their women and girls end up being more successful. today i want to discuss an issue that relates to each of these challenges. it should concern every person, because it is a debasement of our common humanity. it ought to concern every community, because it tears at our social fabric. it ought to concern every business, because it distorts markets.
